Description

The Keysight E4460B will protect your equipment with a full length Plexiglas front door. An attractive, transparent smoke-colored Plexiglas front door provides a consistent appearance to the rack and is lockable to control access to the instruments and peripherals mounted in the rack. The front door is also useful for keeping equipment free from dust.

The E4460B is compatible with the Keysight E3660B rack.

An extractor fan (E4470A/E4471A) is highly recommended to improve air circulation when a front door is mounted.

Can be installed to hinge on either the left or right side for maximum flexibility
